[R] Package seems to be present but library don't find it

[Marc Girondot]

In case someone has the competence to check, the file is here:

setwd("~")

download.file("http://www.ese.u-psud.fr/epc/conservation/r-scripts/HelloWorld_1.0.tar.gz", 
"HelloWorld_1.0.tar.gz")

install.packages("HelloWorld_1.0.tar.gz", repos = NULL)

Thanks a lot

Marc
